Unofficial VirtualDub Support Forums > VirtualDub Filters and Filter Development > New FLV and Matroska plugins for VirtualDub

Posted by: fccHandler Sep 26 2010, 04:58 AM

Moitah's old FLV plugin was starting to show its age. Most of the FLVs I see now use AVC video and AAC audio, and his plugin never supported those. Therefore I took it upon myself to create a brand new FLV plugin from scratch.

As of today I can successfully open all of the FLV files I have, so I guess it's time to go public with it:

http://fcchandler.home.comcast.net/~fcchandler/Plugins/FLV

Known issues:

Not all formats are supported, but I think I support everything that Moitah's filter supported.
VirtualDub can't decompress AAC audio because there is no ACM codec for it. It can be Direct Stream Copied though.
Currently no workaround is implemented for variable frame rate video. A/V sync may suffer in this case.

Enjoy.

Thanks. Personally I don't have much use for this, but it is good to see you are still active.

The video decoding must be done through ffdshow?

Yes - for FLV1 and VP6F.
For AVC - also can use x264vfw.

Thnx

Yep, thanks for the plugin!

how can I decode the flv file through ffdshow?
I mean, I tried to open it in VD, but it shows an err screen

When You install ffdshow do not forget to select VFW interface.

Go to - VFW Configuration (ffdshow video encoder configuration) > Decoder > Codecs - and set support for selected codecs.

Thanks fcchandler!

Saves me from having to use FLVextract to demux files and mux to mp4 with Yamb.

I'm going to go ahead and give you guys a little taste of the other plugin I'm currently working on:

http://fcchandler.home.comcast.net/Plugins/Matroska

Be warned that this is VERY experimental right now. I can open exactly two of my Matroska files with this. But hey, it's a start.

Stay tuned for further developments.

@fccHandler:

Thank you very much for you to start preparing this plugins(Especially Matroska). Of course, will improve over time. This input-plugins will be useful to many people, as your WMV/MPG2/AC3ACM plugins. I wish, you success and patient on this works.

Thank your for your plugins!

Posted by: fccHandler Oct 9 2010, 04:54 AM

v0lt and Dstruct: Thank you for your testing results.

I've uploaded tonight's build, which adds preliminary support for AVC video and AAC audio, and should fix the crash posted by Dstruct:

http://fcchandler.home.comcast.net/Plugins/Matroska

Currently the parsing stage concludes with just four possible outcomes: Success, a "Parse failed" popup, a crash, or a hang. But as I get deeper into this I do plan to implement much better error handling in the future.

I have found one Matroska file in which the parsing is very slow. I mean, like, pathologically slow. I haven't figured out yet what is going on there.

FWIW, my code is based on this specification:

http://www.matroska.org/technical/specs/index.html

However, I have at least one Matroska file which violates that spec. The Info block indicates that it was created using libmkv 0.6.4 and HandBrake 0.9.4. I say it is broken because they have written the MuxingApp field with an id of 0x80, not 0x4D80 as it should be. I've worked around this in the code, but I'm not sure who I should complain to about it...

As with the FLV plugin, you will not be able to decode AAC within VirtualDub. For now it can only be Direct Stream Copied.

Posted by: Gromozeka Oct 9 2010, 08:48 AM

Thanks
But audio aac is not defined in matroska

You can will compilled Faac acm (ac3 acm is)?
source was in sounforge

Posted by: Barough Oct 9 2010, 04:58 PM

Thnx for the update MKV plugin.

Posted by: fccHandler Oct 9 2010, 08:33 PM

Gromozeka, I never say never, but currently I do not have any plans to make an AAC ACM codec.

I found some major bugs in last night's build and have uploaded version 1.2:

http://fcchandler.home.comcast.net/Plugins/Matroska

I added support for MPEG Layer II audio, but it's kind of strange. On my system in File Information I see Unknown tag 0x0050, and yet it plays OK in VirtualDub. I have no idea how that works...

This build also marks a milestone because I can now open all of the Matroska files I have.

Thank you very much for the plugins, i was waiting for so long for something like your matroska input plugin. Direct stream copy seems to be working correctly with it, so cutting a part out of an MKV video (to AVI, but it's ok to me) is finally easy and simple, unlike with mkvmerge. (and it's working correctly, unlike avidemux

)

Thank you for the plugins

Bad that you do not plan faac acm
But matroska plugin work fine - mkv with x264 and aac save to avi (avi played with aac audio good)

now mkv possible to edit

Posted by: fccHandler Oct 10 2010, 06:34 AM

@v0lt: Thanks so much for uploading your test files! I downloaded the first two files, but there is no link to the third file.

The Crank file contains MPEG-2 video and I have no plans to support that right now. (If your third file contains MPEG-2 video then it is likewise unsupported.)

The Offspring video has an unusual Segment size of -1, but that's not necessarily out of spec and it is easy to work around. However, it also contains Windows Media Audio and I'm not sure yet whether it will be possible to support that. I will give it a try though; stay tuned.

Posted by: v0lt Oct 10 2010, 06:57 AM

@fccHandler: The third file has a size of ~ 400MB. Yes, it's MPEG-2 video.

You can not rush. It's just two files with MPEG-2 video.

IMHO, this is an example of the wrong file. Maybe it is unique.

What do you think about decoding AAC through http://www.audiocoding.com/faad2.html?
For example, MPEG-2 plugin has a built-in decoder for MPEG-Audio, and VirtualDub has a built-in decoder for MJPEG and DV.
Make decoding using DLL will be easier than doing the ACM codec?

Posted by: levicki Oct 16 2010, 10:02 PM

@fccHandler:

There are several problems with matroska plugin for me (in order of importance):

1. I get "missing codec" for MKV file with 'AVC1' video FourCC. Do I need to have VFW x264 decoder? I have CoreAVC Professional installed (which includes Haali Media Splitter), and the same file opens and renders correctly using DShowInputDriver.vdplugin.

2. I cannot choose audio language -- your plugin doesn't detect and forward multiple audio streams to VirtualDub.

3. Parsing 8129 MB MKV file takes a lot of time (1m15s) on http://levicki.net/gear/. DShowInputDriver.vdplugin opens the same file instantly.

Regards,
Igor

Posted by: fccHandler Oct 17 2010, 06:37 AM

v0lt:
I do not want to embed any audio/video decoders into the plugin. The Correct™ way to handle this problem is via Windows ACM. So I might be inspired to create an AAC ACM codec someday, but currently I am not planning to do so.

You need a VCM decoder for the 'AVC1' FOURCC. I am using the http://ffdshow-tryout.sourceforge.net/download.php on my system.

I imagine that an 8 GB file will take a long time to parse. The Matroska format supports a sample index, which in theory should eliminate the need to parse. But that index is not guaranteed to be present, and for that reason I am not utilizing it now. Maybe in the future I can support it.

Can't you detect if index is there and use it (or not) accordingly? During parsing, CPU utilisation floats between 1% and 3%. I understand it can be an I/O intensive operation but it still sounds way too slow. Perhaps some profiling is in order?

I think I will wait for Matroska plugin to get improved a bit, and in the meantime I will share my current setup with you:

1. I got GTX 470 video card (CUDA capable, a bit expensive but there are cheaper cards out there as well to chose from)
2. I bought CoreAVC 2.0 Professional for $10 (includes Haali Media Splitter)
3. I removed Matroska, WMV and QuickTime input plugins
4. I uninstalled QuickTime codecs and all other codecs I know are bad
5. I installed DirectShow Input Driver 0.8
6. I registered MP4, MOV, MKV and WMV to DirectShow Input Driver
7. I patched VirtualDub 1.9.10 so it doesn't use internal ASF input driver (otherwise you can't load WMV from file associations or command line)

Results:
1. I can open and decode all WMV files -- with WMV plugin I had some files which were giving me "missing codec" message (because WMV9VCM doesn't handle older codec versions)
2. I can open HD MOV files from my Canon 5D Mark II camera -- they were being decoded using QuickTime before, and only frames decoded properly were keyframes. Those files use AVC1 so they are decoded in hardware by CoreAVC
3. I can open MP4 files encoded with H264 and have them decoded in hardware too
4. I can open MKV files with AVC1 and H264 -- they are opened instantly, decoded using CoreAVC on a GPU and seeking is instant

The only thing missing is:

1. support for choosing audio stream for MKV
2. file information no longer shows video and audio codec info because of configuration dialog which is not very good

levicki:
Indexing speed is not a priority for me right now. Personally I am satisfied that Matroska files can be opened at all, regardless of how long it takes. That's really all I wanted from this plugin. I do plan to address performance issues in the future though.

I've uploaded a new version 1.3 with some improvements:
http://fcchandler.home.comcast.net/Plugins/Matroska

I added support for the "Header Stripping" algorithm which I have been seeing in newer Matroska files.

Windows Media Audio can be direct stream copied, but it will not play in VirtualDub, although it should. I don't know yet why it fails to play.

I am having issues with the AVC decoder of ffdshow-tryouts 1.0.3.1316. It crashes sometimes with newer AVC files. Nevertheless I can direct stream copy that AVC into an AVI and play it back with MPlayer, no problem. From this I conclude that my unwrapping of the raw AVC frames is correct, but the ffdshow VFW decoder is bugged. Just be aware of that if you see video corruption in VirtualDub.

Posted by: v0lt Oct 23 2010, 05:20 AM

Thank you!

I would like to see a selection of audio tracks, as is done for AVI-files. Is it real?

Posted by: fccHandler Oct 23 2010, 05:41 AM

Oh yes, I definitely plan to implement the capability to choose from multiple audio tracks. That is high on my priorities.

Posted by: fccHandler Oct 23 2010, 05:30 PM

Just to follow up on what I wrote last night, the AVC corruption I was seeing was definitely due to an old version of ffdshow-tryouts. I installed their http://ffdshow-tryout.sourceforge.net/download.php and that fixed it.

I'm afraid I don't know enough about DTS to implement support for it yet. It depends entirely on whether it can be packaged into a wave format and delivered through ACM. Also I don't currently have any examples to work with; I would have to download something I guess...

As I stated years ago it is impossible to support everything that Matroska can contain, within the limitations imposed by VirtualDub, VFW, and ACM. I am slowly learning that each video and audio format presents its own unique challenge and I pretty much have to tackle them individually one at a time, as I encounter them.

I will probably upload a new build tonight, because I finally have v0lt's Offspring video playing and I've nearly finished the support for multiple audio tracks.

Posted by: fccHandler Oct 24 2010, 05:43 AM

As promised, here is tonight's build:
http://fcchandler.home.comcast.net/Plugins/Matroska

I've inadvertently discovered a fatal flaw in this plugin. So far I have assumed that MP3 audio in Matroska is packaged in such a way that each audio "block" is exactly one MPEG frame. Unfortunately that is not guaranteed, and I have one Matroska file which blatantly demonstrates that. Aargh...

Fixing this flaw will involve a lot of work; furthermore I presume that it is not guaranteed for the other compressed audio formats either. Probably I've just been lucky.

The symptom of the problem (should you encounter it) is that seeking to a random position in VirtualDub throws the audio and video out of sync. The sync is OK if you play straight through from the beginning; only seeking is broken.

But I call it "fatal" because your output AVI will exhibit the same problem when seeking, and that is really bad news. I will work on fixing it.

If you want me to troubleshoot these issues then I will need more information about the files which are failing. If you can post a link to the file that would be ideal, otherwise try to find out what codecs are involved. Note that some codecs are intentionally not supported, like MPEG-2 video and DTS audio for example.

I've uploaded a new build which fixes the issue described in http://forums.virtualdub.org/index.php?act=ST&f=15&t=19329, and hopefully fixes the sync issue I described in my previous post:

Hi, fccHandler

I had used a new plugin of your site (http://fcchandler.home.comcast.net/~fcchandler/) but before a release of your new plugin, I had found a plugin in other site with a plugin for FLV (http://www.moitah.net/download/latest/FLV_Input_Driver.zip)- old plugin. The old moitah plugin runs normaly FLV videos in Input exibition side. The FLV format have many codecs, and I suggest that you to do as author of other mentioned plugin, let a codec/ decoder for download of own user, only then will be possible to have a larger support. The decoder necessary for interprete VP6 are at: http://www.4shared.com/file/wVx1iOS7/vp6_decoder.html, and with this driver, I would can use a plugin of moitah, and in your plugin maybe it is not necessary. In your WMV3 plugin you made this, let a decoder in choice of user for download and so then function better.

Edit: Since the link at http://http:/minus.com is no longer available, the new link that not expires are now at Google Drive:

https://docs.google.com/file/d/0B2P9tmmpSwF-eUdEMWJXVUhMWXc/edit?usp=sharing
(vp6 decoder.zip)

4Shared has blocked for only registered users do download of the shared files.

Minus.com: The http://minus.com has changed the site policy, and ended leaving unavailable for download all the files that are not images.

Edit (2): My http://minus.com account and online folder were deleted, because for a long time this sharing service was not working, and was not giving features of a sharing site that I previously and initially, wanted.

I have tested your last release Version 1.1 (October 31, 2010 last update) and the problem persists (load, but not runs correctly exibition) (in one video FLV).

I have tested the last updated November 24, 2010, and now the video loads, and I have percepted that Input side exibition stayed freezed, no runs any video, and in the moitah FLV plugin this problem do not occurs.

Thank for update, and I wait the problem solution for the problem that repeats also in other plugins too as the WMV.
L.H.V.F.

I tested the files again. There is a problem opening the files in the latest versions of the Matroska plugin.
v1.3 - opens
v1.4 - "Parse failed."
v1.5 - "ParseTrackEntry 2 failed."
sample - http://www.mediafire.com/?99q2c8h0u4aixd0
I see the problem on a large number of files.

Posted by: fccHandler Nov 20 2010, 07:11 AM

Sorry to have taken so long to respond. I've been very busy with other stuff lately.

The problem was that your file contains an unsupported AAC-LC SBR audio track. I suppose the old version 1.3 just ignored it, but later versions abort when they see this track, although the other tracks are OK.

This was definitely a bug because the plugin should never abort due to an unsupported audio track. I've fixed that bug, and added specific support for your AAC-LC SBR track (direct stream copy only).

BTW, I noticed an odd aspect ratio change when copying your video into an AVI file. I don't know why that happens; there is nothing in the plugin which looks at or modifies aspect ratio information...

Anyway, here is the new version 1.6:

Posted by: fccHandler Nov 21 2010, 05:54 PM

Oops, the File Information dialog "Stream x of x" text field is not updating correctly in the new Matroska plugin. I will fix that in the next release.

Posted by: fccHandler Nov 25 2010, 04:49 AM

I've added support for AAC-LC (not SBR) as seen in the most recent AAC sample posted by v0lt:

http://fcchandler.home.comcast.net/Plugins/Matroska

I've also looked into Vorbis, but I'm not sure whether I want to support it yet. The proven way to package Vorbis in an AVI file (compatible with Vorbis ACM and ffdshow) is vastly different from the way that it is packaged in Matroska.

In Matroska, the Vorbis audio is pretty much dumped raw as is. But in AVI it appears to be wrapped into an Ogg container within the AVI container. I would probably have to write something like an Ogg multiplexer to repackage the Vorbis stream in real time for AVI delivery. That could get really ugly and I haven't decided yet if I want to pursue it.

Posted by: v0lt Nov 25 2010, 06:34 AM

Thank you for support AAC-LC!

Can not be packaged Vorbis in AVI. Otherwise, there will be problems. OGM format has been coined for it. But it died. In theory, vorbis-stream can be placed in the matroska with http://forums.virtualdub.org/index.php?act=ST&f=15&t=17508&st=0.

Posted by: jpsdr Nov 25 2010, 08:40 AM

Just for information, the fact is that Vorbis in mkv is not uncommun. For anime, at least, there is regularly the audio in Vorbis. It's not the most commun format, but it's not the most unusual.
In my case, the audio format i usualy encounter in mkv are :
AC3, DTS, FLAC (16 and 24bits), Vorbis, AAC.
Sometimes TrueHD alone (without AC3 core), but this one is realy unusual.

Do you mean that you are not able to load the source code into Visual Studio 2008? The C++ source code was created with Visual Studio 2005, but it should load seamlessly into Visual Studio 2008. I would be very surprised if that is not true. There is no .NET code involved.

I could've sworn that I was opening H264/AAC FLV before with this FLV plugin but now I can't open any. I can open all the other FLV but not H264/AAC. I can use an ffmpeg .bat file to convert them all to MKV and then use the MKV plugin to open them but I cannot open them in an FLV container unless I use the directshow input driver.

When I try to open the H264 FLV with the FLV plugin, I get two very small green boxes. Virtualdub says it's using ffdshow to open the video and no audio. If I advance thriugh the movie, I can see the frames changing but it's just a very small corner of the frame. If I use the resize filter, I can blow the output frame to the right size but it still only shows the very corner. If it's a few blue pixels then the whole frame is blue.

I can only assume that Virtualdub is using the wrong splitter?

I deleted the folder that I had them in. They all came from the same website so there was either something wrong with the files or replay media catcher messed them up when it downloaded them. They were all downloaded at the same time.

I have 4 or 5 downloads from youtube and they all open correctly with the plugin.

Weird thing was that in mediainfo, the properties looked pretty much identical as the youtube FLVs so I don't know what the problem was.

Do you know what software I can download to get "codecs" to show in Windows Explorer's View Details columns? I had it showing before but after reinstalling XP Pro, it no longer shows codecs since codecs is not a default column in XP. I've installed a few programs that I had before and they added more column options but still no codecs. I've googled many times ut cannot find how to get codecs to show in the Details columns. One guy said he reinstalled his codec pack and got it back but did not say which codec pack. I don't really want to install codec packs on my PC.

Posted by: DarrellS Dec 13 2010, 12:08 AM

I Guess the problem with the FLV files is that there is no meta data. I used ffmpeg to convert H264/AAC MKVs to FLV and have the same problem so I assume that's how the other H264 FLVs were created. That is the easiest way to turn an MP4 or MKV into an FLV, with the copy command.

EDIT: I guess that's not the problem either. The only thing I can do to get Virtualdub to open the files correctly with the plugin is to re-encode the files with Super. I can't just copy the streams into a new FLV container with the metadata.

EDIT: ...or batch convert all the FLVs to MKVs with ffmpeg and just use the MKV plugin to open them.

Hi, fccHandler

I had downloaded a video of an JW video Player, with DownloadHelper Firefox add-on, and when I have tested this FLV video, in many video players there are problems. This FLV not opens in any video player, and when I saw the file information in MediaInfo, and I discovered that is Moyea FLV Lib. Until the K-Lite Mega Codec have need the plugin patch for load this video codec correctly, and normaly only loads the audio. Then I tryed to test in VirtualDub. The moitah plugin runs the video without library, and fccHandler FLV plugin show the message "FLV not supported".
I wish FLV fccHandler plugin would has support this format, and I let available the link for this video: http://www.4shared.com/video/M8MP39gx/20101214bl3_1292371138.html

@L.H.V.F.: With normal players you get only audio but it works fine with VLC.
The file contains VP6 video.

I don't know if it is a bug or just a missing feature but the extracted raw audio (aac audio from flv file) isn't playable, instead if I extract it with FLV Extract it is playable.

If you export the audio in VirtualDub then you truly get the raw AAC, and in my experience it is not playable. I suspect (like Windows Media Audio) that it has to be wrapped in some container to be playable. I could be wrong though and I will need to research it...

@fcchandler:

Again, huge thanks for your awesome work. Great plugins. ^^

Posted by: ale5000 Dec 20 2010, 12:30 AM

@fcchandler: I also thank you for your work.

First set of test files (4.87 MB): http://www.megaupload.com/?d=3PA6X7Z0
Problems:
1) Open the .flv in VirtualDub you will see a green frame (a similar problem happen also with the Matroska plugin)
2) Open the .flv in VirtualDub and then look at file information:
- It show Audio sampling rate as 96000 Hz instead of 44100 Hz
- The video frame rate is 29.916 fps for mediainfo but 29.909 for your plugin (not sure which is the right one)
- The audio duration is 2:26 for mediainfo but 2:27 for your plugin (not sure which is the right one)
- The video bitrate is 198 Kbps for mediainfo but 196 Kbps for your plugin (not sure which is the right one)
- Tell me if the problem is in MediaInfo so I can report it.
3) The .bin file is the one extracted by VirtualDub (not playable) instead the .aac file is the one extracted by FLV Extract (so you can see the differences)

Second set of test files (233.06 MB): http://www.megaupload.com/?d=IDXGWGY6
Problems:
1) This contains the problematic .flv file made from "Moyea FLV Lib" + other versions with the same video/audio but in other containers.

That's indeed true. Raw AAC data is not playable. What is usually referred to as 'raw AAC' though is AAC with ADTS headers, which IS playable.

.FLV file with vp6a video (it has alpha channel): http://user.augmented-reality.it/~josef/tmp/alpha_vid.flv

The flv input plugin can open it but it only show black video.

Posted by: niko84 Dec 21 2010, 12:50 AM

I am having problems to use the FLV plugin as well with symptoms similar to the ones reported earlier.

My .flv file is H.264 and I can open/load it with Virtualdub but I only get a green screen. If I play the video the screen turns black and the frame counter starts to increment but no video.

I am on windows 7 and I have installed x264vfw.

Any help would be appreciated.

No problem.

PS: I have noticed a minor problem, the Matroska plugin doesn't appears under Audio => Audio from other file...

Edit: In the preferences of VirtualDub I select "Prefer internal audio decoders over installed third-party codecs"
then I open an .mkv file but in File => File information... it still say "ACM codec" => "Lame MP3" instead of the internal MP3 decoder.

This option doesn't work for input plugins -- they can only request video decoders from the host, not audio decoders.

I don't remember which of you sent me these files, but here's what I've found:

alpha_vid.flv - fixed
It turns out that the 'VP6A' codec is totally broken in ffdshow. However, the 'VP6F' codec seems to work OK with VP6A data, so I am now using that FOURCC instead. (This is also what Moitah's plugin does.)

20101214bl3_1292371138.flv - fixed
The problem with this video is that it does not begin with a keyframe. I have added support for it anyway.

I've also fixed Matroska to appear in the "Audio from other files" dialog.

Regarding the AAC stuff, I am still investigating.

Merry Christmas everyone.

About the plugins, I have questioned my teacher of my Technical course of Informatic, and he say to me for runs as Administrator account first, for the problems with programs made with Visual Studio. He think that problem comes of my account with limited privileges, and also for in this case can't write in the folder "Program Files" ("Arquivo de Programas" - in the windows in portuguese), and folder "WINDOWS\System32", as I have problems with many programs, for this I use .zip programs, that not needed install. Other thing that he say to me, and I not have certain, are the programs compilated with Visual Studio, not should need to use the .NET Framework, he say that it is not possible, is needed to use some function of language, but only is possible not use a graphical tool recourses for do the program, and it uses a .NET Framework anyway.

Moitah plugin not have the same problem, and I have use both.

PS2: And about the frame 0 almost always green?

I did find the cause, but I'm not quite sure yet what I am supposed to put there. The high-level FLV header says 44100, but the low-level AAC header says 22050 (presumably due to SBR). So the question is what should go into the WAVEFORMAT header, and I don't have a good answer yet. In practice it doesn't seem to matter, but still a decision needs to be made and I want it to be the "correct" one. Still looking into it...

I have also seen that frame 0 is green in a lot of my FLV and MKV files. I suspect it might be the ffdshow decoders implementing a one-frame delay, i.e., it eats that frame for future reference but gives me nothing in return. If so then it may not be fixable.

Posted by: ale5000 Dec 25 2010, 04:12 AM

With MediaInfo you can get more info.

Example:
Audio #1
ID : 1
Format : AAC
Format/Info : Advanced Audio Codec
Format profile : HE-AAC / LC
Codec ID : A_AAC
Duration : 24mn 40s
Channel(s) : 6 channels
Channel positions : Front: L C R, Side: L R, LFE
Sampling rate : 48.0 KHz / 24.0 KHz
Compression mode : Lossy
Title : AAC 5.1
Language : English

Audio #2
ID : 2
Format : AAC
Format/Info : Advanced Audio Codec
Format profile : HE-AACv2 / HE-AAC / LC
Codec ID : A_AAC
Duration : 24mn 40s
Channel(s) : 2 channels / 1 channel / 1 channel
Channel positions : Front: L R / Front: C / Front: C
Sampling rate : 48.0 KHz / 48.0 KHz / 24.0 KHz
Compression mode : Lossy
Title : AAC 2.0
Language : Japanese

It is retro-compatible, for example for the second audio track you get =>
- In players that support only LC you get: 1 channel, 24.0 KHz
- In players that support also HE-AAC you get: 1 channel, 48.0 KHz
- In players that support also HE-AACv2 you get: 2 channel, 48.0 KHz

Posted by: fccHandler Dec 25 2010, 05:34 AM

I'm sure you didn't get that info from an .flv file! The .flv format is very sparse and doesn't even support multiple audio tracks.

I ran MediaInfo on your Hatsune Miku .flv and got the following for the audio track:

Format: AAC
Format/Info: Advanced Audio Codec
Format profile: LC
Duration: 2mn 26s
Bit rate: 63.0 Kbps
Channel(s): 2 channels
Channel positions: Front: L R
Sampling rate: 22.05 KHz
Bit depth: 16 bits
Compression mode: Lossy
Stream size: 1.10 MiB (24%)

But I believe that profile is incorrect because (you say) it is an SBR stream. So my only real doubt is what is the "correct" value to go into the WAVEFORMAT nSamplesPerSec field. I am leaning towards 22050 being the correct value.

Posted by: ale5000 Dec 25 2010, 12:38 PM

There isn't SBR in Hatsune Miku Sings Levan Polka.flv file, sampling rate is really 22.05 KHz
It was a mistake, because I have now discovered that libfaad2 used by ffdshow-tryout for decoding aac erroneously set as SBR all aac tracks with low sampling rate.

Many players/decoders upscale all aac files with low sampling rate to 44100 Hz in any case.
The "Audio output sampling frequency" in mkv header is wrong sometimes.

You can't use only SBR / PS info from the header in any container because often they aren't declared, you need to directly parse aac like mediainfo (look for implicit SBR / PS detection).

Edit: The file from the example is different, here the HE-AAC - HE-AACv2 audio test file (file from the example): http://www.megaupload.com/?d=NUBLKZYJ
It is an .mkv with 2 audio tracks (no video track otherwise the file would be a lot bigger).

Edit2: You can see the aac parser here: http://mediainfo.svn.sourceforge.net/viewvc/mediainfo/MediaInfoLib/trunk/Source/MediaInfo/Audio/File_Aac.cpp

I'm not complaining, of course, but i'm curious to know why...
I've on my PC installed Haali splitter, ffdshow (+VDub filter), and Directshow plugin of Avery Lee.

Hi, fccHandler

I have tested your compilation of Visual C++ 6.0, and the problem that I have noticed about the Input side no loads a video to be continued in limited account user. But now I have opened in Administrator account and the K-Lite Mega Codec have indicated that various codec registry entries are truncated. I think this strange because runs a video in limited user, and Administrator not (?). The moitah plugin no needs a Administrator account for works right.

After I test the VirtualDub with other instalation (MISSING CODEC) in Administrator account, I will go post a reply of the results.

I have tested your plugins in Administrator account, after uninstall earlier version with problems, and now in Administrator account the plugins works right. Again I would say that Moitah plugin works equal in any user mode.
Snapshot of my Control Panel: http://img339.imageshack.us/i/imageofcontrolpanel.png/

The Visual Studio 2008 of accord with the my teacher has a different functions, others no exists more, and that would can there problems in different compilators (2005-2008). I have Visual C++ 2008.

I can see one problem in the last update of FLV plugin in this video: 20101214bl3_1292371138.flv http://img69.imageshack.us/i/snapshotgreenscreen.png/

Matroska also has a green color in the first few frames, when I converted to AVI (xvid) he also gets the green frames, sometimes it happens that the converted MKV to AVI is not correct.

Posted by: ale5000 Dec 28 2010, 04:50 PM

@L.H.V.F.: If the plugin appears in the list, but it just say MISSING CODEC it can also be that the plugin is working correctly but it is ffdshow-tryout that isn't working correctly (I'm talking about the VFW part of ffdshow-tryout).
I'm not sure if the Moitah plugin is using VFW or not.

I was referring about the different forms of works of the plugins. The Administrator account runs normally any video, and differently one limited account have problems, that I have noticed many times, this account not loads a video in Input side. The Moitah plugin runs a video without problems, independently of user hierarchy. The problem of (MISSING CODEC) has been solved, was only I uninstall the earlier K-Lite Mega Codec, for install other more recent that problem of codecs that I can solved this problem. Other problems that I can see is in this video 20101214bl3_1292371138.flv, this problem is independent of user mode, the fccHandler FLV plugin show a green screen in the first "key" frame, and in the Moitah plugin not, shows only a black frame.

Snapshot of my control Panel: http://img339.imageshack.us/i/imageofcontrolpanel.png/

The fccHanlder developer made a same program compilated with Visual C++ 6.0, and the first problem persists under a limited user account (...Input side not loads a video...). Other problems are secondary.

@L.H.V.F.:
The file "20101214bl3_1292371138.flv" works well with the latest version of the flv plugin of fcchandler.
The problem of the first frame being green isn't specific to .flv files, you get it also for .mkv for example.
I really don't think that the compiler is the problem and also just because it is compiled with Visual Studio doesn't necessarely mean that the file depend on .net framework.

I haven't had time to try on a limited user so I cannot say anything for now.

Posted by: Loadus Dec 31 2010, 11:48 AM

@fcchandler:
I remember that you weren't very fond of a plugin that writes stuff on it's own, but I'm still requesting this.

Could you cook up a version of the MKV plugin and your (awesome) MPEG-2 plugin that automatically write an index file right next to the original file (ie. without going to advanced settings)? I open the files usually with SendTo, and if there is an existing index, VirtualDub will open the file in a zap.

If it's too much hassle and work, then no probs.

Thx again for these awesome plugins, especially the MPEG-2 one. ^^

Hi ale5000 and fccHandler

Now I have tested on my other computer, under limited user account, this windows xp SP3 original and constantly updated, and the plugin works correctly, runs the video in Input Side. The problem, how I can see, comes of the part of the compilator. The other computer has only Visual C++ 2008 as compilator, and the windows original has both, 2005 and 2008 in the library. My teacher was right in the incompatibility of the compilators, is necessary to have both. However this windows are formated in FAT32, instead of NTFS, and not blocks to write in Program Files (Arquivo de Programas), and WINDOWS\System32...

Then I would went search a decoder, and at time I found this: http://www.4shared.com/file/wVx1iOS7/vp6_decoder.html.

I don't know if I not would had a decoder if the moitah plugin would go function correctly, but after that I had installed the On2 VP6 decoder and the error disappeared in the moitah FLV Input Driver.

In other case, in the first release of WMV fccHandler plugin, it have showed a message in one video that I have, saying of fault of codec. Then I installed a decoder and the problems was solved. The video in WMV, that I will go to post one day, despite of have the codecs with K-Lite Mega Codec, stay missing a codec anyway, on the video or audio until install a decoder. The codec of last file mentioned is a hack, and this video works different of official, and needs to install a specific codec/decoder of microsoft.

Sorry to be so late responding; I missed your post the first time around.

The only thing that bothers me about your scenario is that it would need to happen automatically without giving the user a choice. That's out of the question.

Instead, I think the best way to do this would be to have an extended open option checkbox (unchecked by default) which you can check to enable the feature. Once checked, the plugin stores that option in the registry so it sticks.

I don't think the coding in this case will be as much of a hassle as it was for the MPEG-2 plugin, so I will definitely consider adding the feature. You will read about it here if/when I do.

WebM is a digital multimedia container file format promoted by the open-source WebM Project. It comprises a subset of the Matroska multimedia container format.

PS: MKVtoolnix can create them => http://www.bunkus.org/videotools/mkvtoolnix/
To create a .webm / .webmv / .webma file drag a video over "mkvmerge GUI", go on Global and check "Create WebM compliant file", etc.
To create a .mk3d drag a video over "mkvmerge GUI", select the video track, go on "Format specific options" and set "Stereoscopy" (I have never used it so I don't really know what it means).

Posted by: fccHandler Feb 5 2011, 06:13 PM

Regarding .webm and .weba, they are subsets of Matroska which allow only VP8 video and/or Vorbis audio. The plugin doesn't currently support either of these codecs, so until it does (if ever) there is no reason to add those extensions.

Regarding .mk3d, all this does is add a value to the stream (StereoMode=n). It seems intended to specify a means to encode two stereo video tracks, one for the left eye and one for the right. If you are not actually muxing stereo video streams, you should turn this off. Consequently I will not add this extension because I have no idea yet how I would support stereo video in VirtualDub.

You friggin' rock, m8. Let me know if you ever need graphics for anything - icons, logos etc. I owe you a lot.

@fccHandler: In the dialog it say "[filename].mkvindex" while the file created has the extension ".mkidx".

Oops, that's left over from when I was trying to decide what the extension would be. Will fix in the next release.

QUOTE (ale5000 @ Feb 6 2011, 05:16 AM)

Also the .mkidx file cannot by opened unless you manually select "Matroska files" from the drop down list.

I didn't plan to allow opening .mkidx files directly, but I might add that feature later. Right now, the fact that you can open it by force is a bug.

Regarding Vorbis, it's been discussed before in this thread. I would like to add support, but it will surely be complex and I can't say when I will get around to it.

QUOTE (ale5000 @ Feb 6 2011, 02:02 PM)

I thought that the function of writing and index to file was for opening later the index file (to open the video with parsing it).

No, in VirtualDub you always open the .mkv file, not the .mkidx file. What happens is the plugin looks for a previously saved .mkidx file in the same folder and with the same name as the .mkv file. If the .mkidx file exists, then it automatically loads the index from that, which is like 1000 times faster than doing a full parse of the .mkv.

In the future I will probably add the ability to open the .mkidx file directly, but currently it doesn't work.

To support Vorbis I have a pretty good idea of what I need to do; it's just a matter of deciding how and where to implement it. I think it is going to be difficult to do without turning the current code into a huge mess, and to be really honest Vorbis is kind of low on my priorities.

Hmm, seems that "Save as default" is not having the desired effect, but I think I know why. Will fix soon.

FIXED (2.1)

Posted by: fccHandler Feb 12 2011, 01:30 AM

Weird. The video format (BITMAPINFO) pointer is NULL, and that's not ever supposed to happen.

At what point did it crash: before, during, or at the end of the parsing stage?

Had you previously saved a .mkidx file alongside this video?

Please try this older version 1.7 and let me know if you see the same crash:
http://fcchandler.home.comcast.net/Matroska17.zip

Also would you be able to extract the first 4 KB of this file and post it? It would be helpful for me to examine the Matroska headers; maybe there is something unusual in there.

EDIT: Nevermind.
This is an old bug come back to haunt me. I will fix it tonight.

Posted by: fccHandler Feb 15 2011, 02:17 AM

The honest answer is, I don't know. I'm not really sure yet what causes the green frames.

Posted by: JaliM Feb 17 2011, 08:20 AM

I have a FLV (AVC+AAC) file dl from Internet TV. If I import to VDub (using FLV fcchandler's filter) the AVC stream is detected but audio AAC stream not, VD info file audio section says nothing (empty).
If I convert FLV to MKV with no audio or video recompression and import to VDub with Matroska fcchandler's filter, then AVC+AAC are detected properly, then I can edit and export to AVI with 'Direct Stream copy' without any problem in A/V sync.!!.

Is it easy to implement an AAC source-parser for FLV VD filter as MKV does? In case it is possible, the 'Direct Stream copy' for Video and Audio could be achived without streams decompression as MKV does?

It should simplify the automation for processes and will avoid the use of other 3rd party video encoders such as Avidemux/FFmpeg to convert firstly FLV to MKV before using VirtualDub.

I upload a FLV sample in http://www.mediafire.com/?grigmz19ee5ivuq to test.

Thanks,

But direct Stream copy is not possible (I mean without decompreesion-keeping AVC and AAC in resulting AVI)

Thank you JaliM for providing a sample file. The problem was a bug in my FLV plugin. (One of the audio blocks in your sample file is written in an unusual way, but it isn't wrong.) I've uploaded version 1.4 to fix the bug:

@fccHandler: Thank you very much for non-stop updates.

This FLV files cannot import with VirtualDub. Error message: "Couldn't parse FLV"

Note: I've tried previously and lastest version(v1.4). No change.

Posted by: JaliM Feb 19 2011, 06:56 PM

Yes, Virtualbub fails to parse.

If you open in Avidemux, it says there is not a 'video stream' but it repairs and opens

so, if you resave to a new FLV file in Avidemux, with no recompresion, then it open in VirtualDub, so I deduce there's a problem in FLV headers...

I can open these files with Moitah's plugin (intalled simultaneously with fccHandler's one, but with lower priority).
It seems fccHandler's plugin fails and skip parsing, allows Moitah's plugin to works.

Posted by: fccHandler Feb 20 2011, 06:38 AM

Thank you pureocean for posting those files. I will see what I can do to fix the problems.

In other news, I have a new AAC ACM decoder up and running in VirtualDub. I've incorporated support into the FLV plugin but I'm not sure yet if it will work with Matroska... Anyway I plan to upload a very experimental build this weekend. Stay tuned.

Posted by: fccHandler Feb 20 2011, 07:39 PM

Well, that's the thing. It won't work with raw AAC, at least not yet. The AAC frames must be wrapped with ADTS headers. I've rewritten the FLV plugin to wrap the frames so currently it will work with FLV. I haven't incorporated the ADTS wrapping code into the Matroska plugin yet. Working on it...

Posted by: fccHandler Feb 20 2011, 08:37 PM

The last two FLV files posted have incorrect TypeFlags in the FLV header. (Remuxing fixes that of course.) I've changed the FLV plugin to ignore the TypeFlags field from now on. The new version also wraps AAC frames with ADTS headers as we discussed:

However there does seem to be a problem with the resulting AVI files after Direct Stream Copy. VirtualDub will play them but MPlayer won't. Bummer. I will have to investigate this to see if it is fixable.

So it mean that it will work only for .flv files and for .avi files "direct stream copied" starting from your FLV plugin?

What about .avi files created from other applications?

The codec will not work for .avi files with raw AAC audio, although I suppose you could remux them into .mkv and then convert them back to .avi with the new Matroska plugin (v2.2). That would build ADTS headers into it.

I don't know about .avi files with AAC created from other applications. It will depend on whether they keep the ADTS headers or not.

It may be possible in the future for the codec to support raw AAC directly but I'm not sure how yet.

Yes. That button cancels any changes you made in the Extended Options dialog. It doesn't stop the Open operation. There is another Cancel button in the parsing dialog which will stop the Open operation (although it doesn't actually cancel it; some portion of the file is still loaded).

I have added this option to Matroska:
http://fcchandler.home.comcast.net/Plugins/Matroska

I will soon add it to FLV as well.

By the way, I do not like having to do this. But I am definitely getting the impression that AAC-in-AVI is required to be stored raw (or at least that most software expects this). I think it's quite possible that this was a decision made long ago by Alex Noé, and now we are stuck with it due to the popularity of his AVI-Mux GUI.

If so, the only good solution is to fix the AAC Codec so that it can deal with raw AAC. I suspect it's possible, but I know it will be hard to do.

Posted by: JaliM Feb 21 2011, 11:55 AM

Hi, I am doing some tests with new AAC ACM Decoder:

I see that if you import MKV/FLV (AVC+AAC) videos with ADTS enabled option, you can play resulting AVI in VLC, Mplayer, and in internal VirtualDub player, but in any other DirectShow player you always need FFDshow Audio with AAC enabled to play, because other AAC Dshow filters fails to render AAC-ADTS files inside AVIs. They expect RAW-AAC such found in other containers: FLV, MP4, MKV. The resulting AVI is therefor mute.

On the other hand if you import MKV/FLV raw stream (without ADTS. AVIMUX GUI mode) the resulting AVI plays on VLC, Mplayer and on ALL directshow players with appropiate AAC filter (CoreAAC, FFDShow Audio, MPC-HC built-in,...) but there's no sound in VirtualDub built-in player

so there's no possibility to recode audio.

I think (if it's possible) the best path to take is the second, allowing to listen audio (transcode too) in VirtualDub. Perhaps allowing ACM AAC filter to interpret RAW AAC (not only ADTS-AAC).

Posted by: JaliM Feb 21 2011, 12:09 PM

I found that Mastroska filter can't import MKA audiofile from Audio>Audio from other file. VDub says 'No supported video track found.' So I suspect that MKV/MKA filter import requieres at least a video track.
While Vdub doesn't support .aac import, I thought that mka (with aac audio) was possible but now I see is not, because of a video track in matroska is mandatory... fccHandler, can this be fixed? Thanks

Bug in AAC ACM codec 1.0:

"Info" says:

Once I viewed this info window and close it, I'll no longer see the "AC-3 ACM Codec" in the Audiocodecs Properties window. I have to close and reopen it to get it back.

VLC 1.1.7+, and any directshow player with FFDshow Audio tryouts (AAC enabled) also plays both AAC-in-AVI versions.

Have you browse the possibility to import MKA files (AAC audio-only) in VirtualDub Matroska filter in Audio>Import audio from file... I mentioned in an earlier post? It is because AAC direct import in VD is not yet possible, or perhaps is easy to implement an AAC filter import (raw and adts')?

Yet the same AVI, with raw AAC, plays correctly for me in Windows Media Player 10 and my current favorite MPlayer (which was taken from smplayer-0.6.8-win32.exe). But neither will play the AAC if it includes ADTS headers. What a mess...

I've reversed the logic of the FLV and Matroska plugins so that raw AAC is the default. (The default is what is used if you've never saved the extended open options.)

I finally added the ability to open Matroska audio-only files (*.mka). For this purpose a fake video stream is generated, same as the WMV plugin. Enjoy.

But no problem on FFDshow's VFW-decoders. As you know, Removed X264 encoder support on FFdshow's VFW interface (I don't mean the decoder feature). Lastest support version (SVN build): 3667

ale5000: You are giving me plenty of busy work.

AAC_test.mka and HE-AACv2 Test.mka:
I suspect these are SBR, plus the Matroska tracks are missing a "Channels" element. Both of these things are problematic right now but I will work on it.

PCM.mka and CRANK (1)-001.mkv:
These two contain PCM audio tracks which are not yet supported, but it is a high priority on my list.

H.264 (1920x1080).mkv:
I didn't notice any problems with this one (using ffdshow). I don't have x264vfw installed.

I understand about the 3-byte start code and will implement a 4-byte code in the next version. As for MediaInfo I can only conclude that it is wrong. It is fairly easy to prove that the output AVI is still 1:02 (1869 frames at 29.97 fps).

As for the missing FOURCC in the File Information dialog, can you post a screen shot? I can't think of any reason that would happen.

I've added support for uncompressed PCM and HE AAC v2, and fixed some cosmetic issues:

http://fcchandler.home.comcast.net/Plugins/Matroska

But to rant, I am not happy about the way HE AAC v2 was muxed in the AAC_test.mka file uploaded by ale5000. There is no metadata in the Matroska headers or the audio private data which enables me to detect Parametric Stereo, and I have had to settle for an ugly hack to make it work. For now I consider the code experimental.

Posted by: BugMaster Mar 6 2011, 01:03 AM

fccHandler
You added zero_byte to 3-byte startcodes only for SPS/PPS but H.264 specs says (B.1.2 Byte stream NAL unit semantics):

zero_byte is a single byte equal to 0x00.
When any of the following conditions are fulfilled, the zero_byte syntax element shall be present:
– the nal_unit_type within the nal_unit( ) is equal to 7 (sequence parameter set) or 8 (picture parameter set),
– the byte stream NAL unit syntax structure contains the first NAL unit of an access unit in decoding order, as specified by subclause 7.4.1.2.3.

So first NAL in every frame must start from 4-byte sequence 0x00, 0x00, 0x00, 0x01 (so in UnwrapAVCFrame also). For you it probably would be less work to change all of them to 4-byte (not only first).

P.S. If you don't have H.264 specs you can freely get them here: http://www.itu.int/rec/T-REC-H.264-201003-I/en

That is exactly why I'm unhappy about it. In my opinion the audio channel configuration should be specified somewhere in the container so I don't have to go digging through the raw audio data to get this info.

HE-AACv2 Test.mka does have the PS flag specified in its AudioSpecificConfig (codec private data), which is exactly where it should be. The AAC_Test.mka is missing this information. I don't have the real AAC spec so I'm not 100% sure whether it is a violation or not.

For the following I haven't verified but it is highly probable:

1) The second audio track (with PS) is detected as Mono instead of Stereo (it isn't related to new changes it happen also with old versions of your plugin)

2) The test file was too big so I cut some parts in the middle.
MPC-HC (using Haali splitter + ffdshow-tryout) can play the parts before and after the cut in the middle instead VirtualDub can see only the initial part of the file.
Seeing the entire "remaining" file is important (but there isn't any urgency) so your plugin can be used to recover broken matroska files.

@fcchandler: Is it possible to add native MPEG2 video to Matroska input plugin? If possible, could be easy to add 'Direct stream copy' feature in video side?
I know the problems in putting MPG in AVI, but, if FFmpeg & Mencoder are able, why not VDUb? (apart from using FFDShow VFW MPEG-in-AVI codec which is possible. But, the newer versions of FFDshow unfortunetely lack encoding features like Xvid, MPEG, x264....

At the moment if I open a MKV with ES MPEG2 native video inside, it is not detected (NO VIDEO STREAM message appears). Otherwise a MKV mpeg2-VFWed video file using FOURCC mpg2 (MPG-in-AVI muxed to MKV with Mkvtoolnix) is detected by the MPEG-in-AVI featured FFDshow VFW decode interface.
Perhaps a MPEG input plugin update could be appreciated allowing 'Video direct stream copy'...

@fcchandler: Test file (HE-AAC test.zip): http://www.multiupload.com/UUT54GJZHE
This is an HE-AAC track with sampling rate: 48.0 KHz (for HE-AAC decoders) / 24.0 KHz (for AAC decoders)
The two sample files are the same track but the first has "HE-AAC flag" not set while in the second file it is set.

You can notice that VirtualDub see 24000Hz on both files (probably because HE-AAC is made to be retrocompatible with software that support only AAC) so the HE-AAC sampling rate should be read in a different way.
This also mean that the Matroska input plugin is writing wrong values of the sampling rate when direct stream copying HE-AAC in avi files.

PS: It would be nice if it show "48000Hz / 24000Hz" in File => File Information... (at least for the HE-AAC in MKV)

In case you can't easily detect the sampling rate from inside the "AAC ACM Codec" you can use this method (that I think is the method that most software uses), if the file is AAC use reported sampling rate instead if the file is HE-AAC use reported sampling rate * 2.

2) The test file was too big so I cut some parts in the middle.
MPC-HC (using Haali splitter + ffdshow-tryout) can play the parts before and after the cut in the middle instead VirtualDub can see only the initial part of the file.
Seeing the entire "remaining" file is important (but there isn't any urgency) so your plugin can be used to recover broken matroska files.

My Matroska plugin is not intended to be a tool to recover broken files. I require the input to conform to the Matroska spec. I do try to work around minor damage, but if needed headers are missing from the beginning of the file, that is game over dude.

I will be looking into native MPEG-2 support and the AAC stuff you posted.

1) The second audio track (with PS) is detected as Mono instead of Stereo (it isn't related to new changes it happen also with old versions of your plugin)

QUOTE (ale5000 @ Mar 24 2011, 12:15 AM)

In all of these cases the containers are overriding the actual AAC properties.

Both AVI files specify 24000 Hz in the audio header, so that is the sampling rate which VirtualDub passes to the AACACM codec. The codec has no control over this; it has to give the client what he asked for.

The second Matroska audio track contains a "Channels" field with a value of 1, which (in my opinion) overrides Parametric Stereo. It is debatable whether it should, but it is a decision I had to make and I will stick to it. If you want this track to play in stereo then you should set Channels to 2, or just omit the Channels field (in which case PS should be detected automatically).

Posted by: ale5000 Mar 26 2011, 04:17 PM

In the posted file (Manual cut.mkv) the header is NOT missing it is just: first good part of the file + some zero where there was data + correct end of the file.

Your plugin seems to stop at the zero.

Posted by: ale5000 Mar 26 2011, 04:28 PM

The AVI header must contain data to play correctly the LC profile of the AAC, to play SBR the decoder must multiply sampling rate * 2.

QUOTE

ADTS sample rates and channel counts are for HE-AAC and HE-AACv2 to try to maintain compatibility with LC only decoders. The good news is that it they are inaccurate in a precise manner. HE-AAC will report half the sample rate and HE-AACv2 will always report a mono stream. This is because HE-AAC adds SBR which double the sample rate and HE-AACv2 adds parametric stereo to SBR and PS turning a mono stream into a stereo image. The SBR payload lives inside an AAC fill element which is ignored by an LC only encoder and the PS payload lives inside the SBR payload.

Some decoders assume SBR if the sample rate <= 24kHz and always decode mono streams to stereo to avoid detecting these features up front. In that case the SBR decoder can be run in a pure upsampling mode if SBR data is not found.

https://www.bunkus.org/bugzilla/show_bug.cgi?id=548 => That's not a bug. HE-AAC files contain _half_ their actual sampling rate in their headers.

By specifying the full sampling rate you are breaking playback in "LC only decoders".

I don't understand you. Who is breaking what exactly? What do you mean by "LC only decoders"?

What is happening with these AVI files is that the decoder (faad2) is detecting SBR and decoding at the full rate, but the clients (VirtualDub and AACACM) mistakenly perceive it as 24000 Hz due to the rate specified in the audio header. In my opinion the header is incorrect; it should specify the true playback rate of 48000 Hz.

But let me ask you; what do you expect to happen when playing one of these files in VirtualDub?

This is how avi with HE-AAC are created in other applications, certainly people that use ffdshow or VLC won't have any problems in both cases but your implementation disagree with the implementation in other apps.

"LC only decoders" => Decoders that support AAC but that don't support HE-AAC.
Decoders that support HE-AAC doesn't use the sampling rate that it is in the AVI headers (so they simply don't care).

QUOTE (fccHandler @ Mar 26 2011, 05:57 PM)

It could be that VirtualDub read the LC sampling rate (24000 Hz in this case) in the AVI header and report it to the AAC ACM Codec then the AAC ACM codec analyze the file, if it is HE-AAC then use sampling rate * 2 otherwise use sampling rate * 1.

Posted by: fccHandler Mar 26 2011, 09:01 PM

I know what the term "LC only decoders" means, actually, I should have said can you give me an example of one. Maybe some hardware devices, but I wouldn't know...

The big problem here is that we are trying to have our cake and eat it too, so to speak. I don't think that you are taking into consideration how the Windows Audio Compression Manager works.

If the MKV plugin lies to VirtualDub that the rate is 24KHz (when it is really SBR 48KHz) then you end up with an AVI with 24KHz in its header. VirtualDub will pass that on to the ACM, and the AAC codec is forced to work with that. He cannot return any other sampling rate but what the client specifies. In fact, that is the problem now with your AVI files; we are returning the true 48KHz but VirtualDub still thinks it is 24KHz.

Also due to the limitations of the ACM it is not possible for AACACM to detect implicit SBR or PS during the initial format negotiations. He does not have access to the audio data until the stream decoding begins, but by that time it is too late because input and output formats have already been decided.

As I see it there are three solutions:

1) AACACM must downsample HE-AAC before returning it to the client. But if we do that then you will never hear the enhanced quality that HE-AAC provides. Might as well just throw out all of that HE-AAC code in faad2.

2) VirtualDub must be made aware of SBR and deal with it on his side (not likely to happen).

3) Don't lie to VirtualDub; tell him the true output sampling rate of the audio so that he can negotiate for that rate with the AAC codec. The problem here is that he will also write that rate into the AVI header which (you say) is wrong.

Currently number 3 is what I have implemented. I do not like the other solutions. If I am breaking somebody's app then so be it, but so far you are the only one who has complained.

PS: I have noticed another problem, I remux an .mkv file (with HE-AAC audio) to .avi with VirtualDub; then I try to remux the resulting avi with MKVtoolnix, it say "This AAC track does not contain valid headers. The extra header size is 7 bytes, expected were 2 or 5 bytes."
Edit: Added test file with bad extra header size created by VirtualDub + Matroska input plugin: http://www.multiupload.com/I07JPARCWZ

The extra bytes are the AudioSpecificConfig defined in the AAC spec, presumably taken straight from the Matroska file. It is 7 bytes because it contains explicit signalling of HE-AAC v2 Parametric Stereo in a second extension field. (Actually it signals that PS is NOT present, which is a bit weird but not out of spec.)

Was the Matroska file created with MKVtoolnix? If so then it is strange that he would write a 7-byte AudioSpecificConfig, but not be able to read it back...

ACM codecs don't work this way -- they have to be able to report the sampling rate based on the header prior to seeing any audio data. This usage of the WAVEFORMATEX structure definitely sounds questionable and I'd say it's broken. Even DirectShow would have problems with this in some circumstances, I'd say.

Incidentally, it is possible for AudioSpecificConfig to be a size other than 2, 5, or 7 bytes (for example, if it contains a custom sampling rate).

Hi, fccHandler

I've used your latest version WMV Input Plugin, and I have installed the codecs adequately of microsoft, and in my experience, I saw a problem with a framerate in videos above of "15.000 fps". It shows wrong the framerate in VirtualDub, in my tests for .wmv. Fortunately, now in my videos .wmv, don't show a green screen in the first key frame, only happens if I open another window of the video board and it gets gray in some moments. I would like to say that video have one problem in "File Information" in VirtualDub, because the video in question, have 29.970 fps, as I can see in MediaInfo, and VirtualDub show that has "29.995 fps".

Could you indicate what is the fail, or correct this in your plugin? I need to use your plugin for convert with some Filters, exclusive for VirtualDub, this video with low resolution: Video Enhancer: http://www.infognition.com/VideoEnhancer/ in test for me, for while. In another video, in earlier version of your plugin, I can make the resolution better with RGB 24 in one video, but when I went tried to convert the framerate (15.000 fps to 30.000fps) (with Lagarith codec), maybe for incorrect schema of framerate, the video output converted stood with something as "30,092 fps" (in my research the maximum of framerate accepted is 30.000 fps in CRT television), but this video was the unique with sucessfully converted framerate that I could make. I will post this video one day, when I install and configure better my codecs, after configuring one more complicated video ( I can open this video in VirtualDub one time.. , but the file in Direct Stream Copy was a .wav with the original file .wma inside, that only can be open in Sound Forge). It showed "???" for codec in tentative of Direct Stream Copy, in SUPER, earlier version. Now in the latest version of SUPER, I can do a direct stream copy of this video finally... VirtualDub doesn't open this audio of video so easily (it made a .wav, with .wma original file inside).

What about setting a custom comunication between VirtualDub and the ACM codec?
Like this:
1) VirtualDub get a request to open an .avi file
2) It looks for an ACM codec
3) Check in the export table of the ACM codec an additional API (for example DriverProcCustom)
4) If it find the API then call it (requesting the two sampling rate and the two channels number, they will be equal for normal aac files) before open the file in the normal way (but with the correct data returned before) otherwise it just behave like usual.

One sampling rate/channels number is for storing in the AVI headers while the others (real values) are for everything else.

I am using a technique similar to what ffmpeg used. It works well with MPlayer, and sort of works with Windows Media Player. It does not work at all with the one Vorbis ACM codec I tried.

http://www.4shared.com/video/eiiHlM4A/DownloadPeople_A_256k.html

How I have said (this video up), in output converted video with Lagarith codec in VirtualDub, stood with "30,092", converting the framerate of "15.000 fps" to "30.000 fps".

The another video, that I have said, is one more complicated to open in VirtualDub. I had opened this another video one time before, but now, I missed the codec/decoder original of microsoft's site (that I downloaded one time) that I need to open it:

http://www.4shared.com/video/qum2L1Dr/frank.html

The video mentioned up, is a DivX made with MPlayer in CLI (in Linux), and had problems with Direct Stream Copy in SUPER earlier version, and is more difficult to open in VirtualDub because of the problem of the audio of it. If anybody know where I can found the specific codec/decoder necessary to open this video above, I thank.

About the file Projeto de Apoio a Continuidade de Estudos(Rede do Saber®).wmv, I see other problems probably related a wrong schema of framerate, and also that the audio suffered a delay, and desynchrony also.

Posted by: fccHandler Apr 9 2011, 01:01 AM

There is no such thing as a "wrong" framerate, because Windows Media files do not have a framerate. The playback rate can change at any time. The WMV plugin reports the average frame rate of the movie, basically the total duration in seconds divided by the total number of video frames. MediaInfo may derive its number differently.

Nevertheless I confirm that your video is grossly out of sync in VirtualDub. I have some theories, but no solution yet. Unfortunately I have not had much free time to work on it. I will not forget about it though.

Posted by: Placio74 Apr 9 2011, 03:56 PM

I guess... MediaInfo just reads average FPS value (for ASF/WMV) from extended stream properties (if it's stored there). Also indicates whether FPS is variable (if stored value is different from calculation). Would be to ask MediaInfo author for sure.

BTW
I think that is a bit better with syncing after remux/repair using AsfBin...

@fccHandler:

Another issue:

This video (http://multimedia.cx/samples/Matroska/x264_no-b-frames.mkv) cannot import. The error box message:

File "x264_no-b-frames.mkv" does not have a video stream.

* * *

And a request:

Matroska plugin use AVC1 as FourCC. Therefore, opening video save as AVC1-FourCC code with direct-stream-copy. Unfortunaley, CyberLink 264 Decoder Filters cannot play properly AVI files based-FourCC AVC1. Especially, if video is saved with smart-rendering method.

I found temporarily solution: I changed AVC1 text to as H264 in inside of Matroska.vdplugin with Hex Editor software(http://mh-nexus.de/en/hxd/). So, CyberLink 264 Decoder Filter can play properly, even if the video is saved with smart-rendering method. If possible, could you change as default FourCC from AVC1 to H264?

Hello folks and a big "Thank You" to fccHandler for FLV input plugin.

I have a problem with some FLV files: they are FLV1 (video) + NellyMoser (audio). I'm using FLVSplitter + ffdshow, and I can open / play / use them with Media Player Classic, AviSynth. Also GraphEdit build the graph and play the file(s). But while I'm trying to open them in VirtualDub via fccHandler's FLV input plugin the audio track is missing. What I'm doing wrong? Please note that in ffdshow Audio decoder NellyMoser is enabled!

Thanks a lot!

...Please note that in ffdshow Audio decoder NellyMoser is enabled!

But it's DirectShow filter/decoder, when FLV input plugin uses ACM codecs for audio (and VfW codecs for video) - unfortunately, ACM codec for Nellymoser does not exist.
Try with DirectShow import driver or FFmpeg input driver or through Avisynth (DirectShowSource or FFmpegSource).

Hi, fccHandler

About a video .wmv that I have uploaded for download, what have you discovered some thing about the problem related to desynchrony in this video with your WMV plugin?:

http://www.4shared.com/video/OE0y3D4v/Projeto_de_Apoio_a_Continuidad.html

I need to convert this video, and to make a DVD with this video, I was planing use the AviSynth for concretize this, according some tutorials, and the AviSynth wiki, that promises total synchrony for VFR videos supported by AviSynth, using .avi in the base.

One question:

Is possible in VirtualDub to resave an .avs, this being an "frameserver", or the unique way is to use VirtualDubMod and the Script Editor (http://forum.doom9.org/archive/index.php/t-68801.html), and apply some filters, to so then save the video in the same format, or exists an .avi split filters for can divide one VFR video? I could to use the AVS2DVD in first case.

I thank an reply.

I still have that video, and I have tested a lot of radical ideas, but I have not been able to fix the sync problem. It's very frustrating. At this point I think you should definitely pursue other methods.

I recommend starting a new thread about it (here and perhaps in other forums) to get ideas from the community. I know there exist many WMV software tools, but I do not have much experience with them so I can't suggest anything myself. Good luck.

Since VirtualDub currently doesn't support multi-channel audio, can be added an extended option to automatically downmix PCM audio in Matroska files to Stereo? (if it is too much complicate don't worry, it isn't an important thing)

I would rather not get into this. It would only be possible with PCM and wouldn't be possible for compressed formats, so that adds yet another "special case" path in the code (which I try to avoid as much as possible).

Another reason is, downmixing more than two channels to stereo is not trivial. It isn't like a simple 50/50 stereo-to-mono mix. I imagine that the weights for each channel would need to be adjustable somehow, which would require a popup dialog and a whole lot of extra code. It's really stepping outside the role of a plugin, in my opinion.

I don't think I'm ready to support those formats yet. Vorbis support is still very experimental. Personally I'm not happy with it at all; it needs more work. Plus I haven't tested VP8 yet so I don't know whether it requires any special handling.

I am dedicating release 2.0 to Boxxy.

Your Boxxy video has its FLV audio sampling rate set to 44100 Hz, but the embedded AAC AudioSpecificConfig gives a sampling rate of 48000 Hz.

I was never sure whether the AAC properties should override the FLV audio properties if they differ, but it turns out that they do. In fact this is stated explicitly in version 10 of the Flash video format specification. I have changed my code accordingly:

It is Vorbis audio. The Vorbis support is very experimental right now, and the worst part is that currently there is no Windows codec which will work with it. Vorbis can be direct stream copied (sort of), but it cannot be played in VirtualDub.

If you just want to play the video, choose Audio -> No Audio to disable the audio track.

To be honest, I've never tested the 64-bit build because I don't own a 64-bit machine myself. However, I can test it at work after the July 4th holiday. I will let you know if I discover any problems with the 64-bit build...

Posted by: fccHandler Jul 10 2011, 04:33 AM

@katz:
I tested the 64-bit build of AC3ACM at work. It was kind of tricky because our 64-bit work machines are servers which do not have audio cards! Nevertheless I was able to confirm it using Veedub64 to decompress the audio to .wav files, then I brought the .wav files home to inspect them. They are indeed silent.

The last 64-bit version which was confirmed to work was version 1.5, but there were significant changes during the migration to 1.6. Sadly I don't have any way to debug this directly, but I suspect a problem with the assembly portion of the code. I explored that part in agonizing detail over the weekend, and put it through a battery of tests.

I found to my surprise that decompression of 5-channel audio was broken, and it probably has been for a long time. It is fixed now.

In addition to that, I made a subtle change to the 64-bit build, and I would like you to test it and let me know if it fixes your problem:

Problem is... Ogg Vorbis CODEC for MSACM supports only own audio tags (0x674F, 0x676F, 0x6750, 0x6751, 0x6771) and does not support 0x566F.

On the other hand... Matroska rather does not support audio tags from this specific codec (but just 0x566F - WAVE_FORMAT_VORBIS).
Also FFmpeg refuses to use those audio tags (from Ogg Vorbis CODEC for MSACM) in Matroska container (as incompatible) - only 0x566F is acceptable.

So... audio with 0x566F id it's Vorbis, however it seems that there is no 'compatible' ACM codec.

I spent this morning trying to combine the separate 32-bit and 64-bit assembly code sources into a single source. I had to use a lot of conditional assembly and the result is horrible to look at, but it definitely helps to have all of the code in one place. I was able to spot another subtle bug specific to the 64-bit build and stereo audio, so definitely try out the new version 1.9:

That is intentional, because the type of ADPCM used in .flv files is not compatible with any of the Windows ADPCM codecs. Therefore the plugin always decompresses it before delivering it to VirtualDub.

Posted by: ale5000 Dec 4 2011, 04:35 PM

Sample files (MPEG-4+AAC.zip - 1.77 MB): http://www.multiupload.com/WKNV379DIQ

Both files contain the same mono audio, but in the mkv it is detected as stereo.

Posted by: fccHandler Dec 4 2011, 07:10 PM

This is a tricky one, because both could be considered correct depending on your point of view...

The Matroska stream has no channel count, so I initially assume mono. However I do detect implicit SBR (indicating HE-AAC v2), therefore implicit PS may be present as well. I can't be certain at this stage, but I go ahead and change the channel count to stereo just in case there is implicit PS.

Although not ideal, this behavior could be considered correct based on the spec:

QUOTE

1.6.6.3 HE AAC v2 Profile Decoder Behavior in Case of Implicit Signaling

If the presence of PS data is backward compatible implicitly signaled (signaling 1, in the list above) the first AudioObjectType signaled is not the PS AOT, and the psPresentFlag is not read from the AudioSpecificConfig(). Hence, the psPresentFlag is set to –1, indicating that implicit signaling of parametric stereo may occur.

Since a received mono stream will result in a stereo output if Parametric Stereo data is present in the stream, the HE AAC v2 Profile decoder shall assume that PS data is available and decide the number of output channels to be two for a single channel element containing SBR data, and thus also possibly PS data. If no PS data is found the mono output shall be mapped to the two opened channels for every single channel element.

And in fact that is what happens in the case of this .mkv.

The QuickTime plugin doesn't attempt to detect SBR or PS (yet). Currently it just uses the channel count and samplerate specified for the track.

Posted by: ale5000 Dec 4 2011, 08:33 PM

To my opinion this is another case where specs aren't updated for real world.
Libavcodec, for example, is able to detect when PS is really present.

Posted by: fccHandler Dec 4 2011, 08:44 PM

Well, he is a codec so he would know.

I can detect it too when it is explicit (i.e., specified in the AudioSpecificConfig header). It is the implicit case that I cannot know ahead of time, since the plugin does not decode.

Posted by: ale5000 Dec 4 2011, 08:54 PM

Well, I think that a minimal decoding (like as MediaInfo is doing) may be useful in the plugin but it is just my opinion

I would say the audio is badly muxed. The audio format is "A_MS/ACM" which means that it provides its own WAVEFORMATEX structure, therefore the plugin does not build a custom one. The problem is the nBlockAlign member of its structure, which is supposed to be the minimum atomic size of an audio block. In your file it is set to 2 bytes, which is not correct for this audio. (The correct value is 32 bytes.)

But I am going to have to work around it anyway, because even if the value was correct it still wouldn't work. The plugin wants the nBlockAlign field to contain the maximum size of an audio block which is 320 bytes in this case.

VirtualDub uses the nBlockAlign value to fetch blocks of audio from the plugin. The error occurs because VirtualDub is asking me for 2 bytes of audio, but that is too small to hold even one block. I will implement a workaround in the next release.
